Using [pyenv][3] to manage your virtual environments makes working on multiple projects, each using a different version of python a breeze.
|
|
|
|
I do all my development on an Apple Macbook running Yosemite and my production environment is a VPS from [Linode][1] running [CentOS 7][2].
|
|
|
|
Here some simple notes on how I setup and use [pyenv][3] :
|
|
|
|
## Installing on Mac OS X ##
|
|
|
|
**Install using [homebrew][5]**
|
|
|
|
```bash
|
|
brew install pyenv pyenv-virtualenv
|
|
```
|
|
|
|
**Update your shell profile (.bashrc or .zshrc) adding the following to it (and restart your terminal)**
|
|
|
|
```bash
|
|
if which pyenv > /dev/null; then eval "$(pyenv init -)"; fi
|
|
if which pyenv-virtualenv-init > /dev/null; then eval "$(pyenv virtualenv-init -)"; fi
|
|
```
|
|
|
|
|
|
## Installing on Linux CentOS 7 ##
|
|
|
|
**Checkout from github**
|
|
|
|
```bash
|
|
git clone https://github.com/yyuu/pyenv.git ~/.pyenv
|
|
git clone https://github.com/yyuu/pyenv-virtualenv.git ~/.pyenv/plugins/pyenv-virtualenv
|
|
```
|
|
|
|
**Update your shell profile (.bashrc or .zshrc) adding the following to it (and restart your terminal)**
|
|
|
|
```bash
|
|
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
|
|
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
|
|
echo 'eval "$(pyenv init -)"' >> ~/.bash_profile
|
|
echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bash_profile
|
|
```
|
|
|
|
## Using pyenv ##
|
|
|
|
**To install a new version of [Python][6]**
|
|
|
|
```bash
|
|
pyenv install <version>
|
|
pyenv rehash
|
|
```
|
|
|
|
**To get a list of [Python][6] versions available**
|
|
|
|
```bash
|
|
pyenv install -l
|
|
```
|
|
|
|
**To create a new virtual environment**
|
|
|
|
```bash
|
|
pyenv virtualenv [pyenv-version] [virtualenv-name]
|
|
```
|
|
|
|
**To use your new virtual environment within your project**
|
|
|
|
1. Change to your projects root directory
|
|
1. Run:
|
|
```bash
|
|
pyenv local [virtualenv-name]
|
|
```
|
|
Note that this is done only the first time you go to your project directory. The wonderful thing about [pyenv][3] is in future when you change directory to your project directory, it will be automatically activated your virtualenv for you.
